DM368 Continuous mode ouput Video with Pink shading

YUV420 captured data from CCDC after Capte_get().

Sujit,

Can you please post the latest updates based on the offline discussions that we had.

Hi all,

the pink color which i had mentioned is now solved.

following is the modification done.

in IPIPE register SRC_HPS the default value 0 has been changed to 1.

i am attaching the video after changing SRC_HPS  to 1.

Still there is a visible line observed on the edges. in the video you can observe above the white color ribbon of the camera.

still Anshuman is trying to find out the cause.

oneshot mode image       : colorissue_oneshot.BMP (420)

continuous mode image  : colorissue.BMP (420)

continuous mode image  : colorissue_chainmode_jpeg_422.BMP (420)

oneshot mode image       : colorissue_oneshot.BMP (420)

continuous mode image  : colorissue.BMP (420) ( The visible line at the edges and at the bootom of the pic is observered only in Chai mode 420 )

continuous mode image  : colorissue_chainmode_jpeg_422.BMP (420)

I also had this problem. will change the register and try according to your solution. thanks.

hi Anshuman,

this problem has been solved.

there was aproblem in capture. gfxAttrs.dim.height  was coming as 1080 ( 1920x1080- 2 M resolution ) , but it was expected to be divisible by 16. so we modified as following.

gfxAttrs.dim.height   = 1088; // 1080;

so now the there is no problem of edges shifted and bootom shifted lines.

i thank you very much for your continuous support and guidence.

Hi,

I got same problem as yours, the color is wrong, my hands become green; I guess that's YUYV & UYVY different.

But I have no idea how to shift one pixel at DM36x. Does anyone know this? Thanks in advance.

Hi JC,

sorry for the late reply.

you can move the SRC_HPS IPPE register to 1 pixel.

you can do it in your dm365_ipipe_hw.c file present inside linux dir char driver folder.

in this file you can find the ipipe register writes are happening inside ipipe_hw_setup() function.

                            regw_ip((config->ipipe_hps) & IPIPE_RSZ_HPS_MASK, IPIPE_SRC_HPS);

config->ipipe_hps value by diffult is coming as 0. change it to 1, which will be and with IPIPE_RSZ_HPS_MASK and result will be written to your IPIPE_SRC_HPS.

hope now you can do this.

Hi, Quote

Since some definitions on my environment, so this function doesn't work to me.

Finally I set camera side register, and it's working.

Thanks anyway.
